Where is Your Username registered
This site is a quick and dirty solution to a question that I often lay awake at night worrying about. Do I have my username registered across every site that I should? What if the next internet humiliation meme just happens to share the username I’ve been using for years, and suddenly people are emailing me asking “hey, is this you ???”. The site is simple. I have a stack of web app urls, the application pings the site using the username you want to check, if it returns a “no user name” error we return that. The site uses Dojo as it does all the checks using Ajax (each check takes a couple of seconds so using Ajax you don’t have to sit and wait 3 minutes for the page to load).

It doesn’t seem to work right. Diigo, Gmail, Yahoo, and several others always respond taken—even if you randomly type 12 character usernames. I know some of these have a lot of registered users, but I don’t think they have that many.
